Values, valuing and evaluation

Professor von Wright has stated that those .concepts relevant to ethics may be divided approximately into three groups The three groups he suggests are value concepts, which include the concepts of good, bad and evil, normative concepts, which include obligation, right, prohibition and permission, and finally, concepts which belong to "the notion of ahuman act" and "notions which are relevant to action" such as desire, end, need, want, intention, motive, reason and will. Von Wright suggests that the study of this third group of concepts could be called a "Philosophical Theory of Man" or "Philosophical Anthropology", for such a study is often embarked upon if the view is held that "one can look for the foundation of morals . in the needs and wants of man and in the specific nature of man as agerit"
